Amazon's Echo smart speakers are sold at a loss, with a $25 billion loss in 5 years for the devices division and $10 billion loss in 2022 for Alexa.
The saturation of Alexa in 100 million homes doesn't offset the massive financial losses incurred by Amazon in the smart speaker market.
Other smart assistants like Google Assistant and Siri are also facing challenges, but Google and Apple are investing in enhancing their respective technologies.
